Application filed November 18, 1915. fierial No. 62,182. Y

T 0 all whom it may concern:

Be it known that I, Soor'r STEWART, a citizen of the United States, residing at Rivesville, in the county of Marion and State of est Virginia, have invented certain new and useful Improvements in Shade- Holding Apparatus, ofwhich the following is a specification.

My invention relates to improvements in means for adjusting window shades and holding them in adjustment in desired positions. 7

An important object of the invention is to provide means of the above mentioned character, which will permit of the free up and down adjustment of the shade, and will hold the same in the desired adjusted position, against undue lateral movement,

A further object of the invention is to provide means of the above mentioned character, which are extremely simple in construction, inexpensive to manufacture, and convenient. in use.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side elevation of apparatus embodying the invention, parts being shown in section, Fig. 2 is a vertically longitudinal sectional View taken on line 2-2 of Fig. 1, Fig. 3 is a perspective view of a cord holding member, secured to the lower sash frame, Fig. 4 is a side elevation with parts removed, of a de-- tachable clamp, carried by the shade, Fig. .5 is a sectional view taken on line 55 of Fig. 4, Fig. 6 is a side elevation, parts omitted, of a diiferent form of cord clamp, and, Fig. 7 is an enlarged horizontal section taken on line 7-7 of Fig. 6.

In the drawings, wherein for the purpose of illustration is shownca preferred embodiment of my invention, the numeral 10 designates a window frame of any well known or preferred construction, within which is mounted upper and lower vertically movable sash frames 11 and 12. These sash frames have connection with cords 13, passed about pulleys 14, carrying weights 15, as is customary.

Secured to the top of the window frame 10 is a depending bracket 16, carrying a pulley 17 engaged by a cord or flexible eleclamp,

ment 18. This cord extends laterally about a pulley 19 and carries a weight 20. The

lower end of the cord 18 carriesa ball 21,-

aud this end of the cord is adapted for in sertion within an opening or slit 22, in a cord holding bracket or device 23, having a base 24, secured to the lower end of the lower sash frame 12, by means of screws 25 or the like. The function of the weight 20 and associated elements is to retain the cord 18. taut, when the lower sashframe 12 is raised and lowered.

The numeral 26 designates a-curtain, the lower end of which is secured to the usual stick 27,. This curtain is attached to a cylinder or roll 28, provided with the usual spring means for rotating'it in one direction to wind the curtain thereon, but the ordinary pawl and ratchet means to hold the cylinder against rotation is omitted, the cylinder bemg tatably mounted-within apertures in brackets 30, attached to the upper end of the upper sash frame 11;

A detachable clamp, by the numeral 31, is secured to the stick 27 for engaging with thefcord 18, whereby the lower end ofjthe'curtainmay be .con nected with this cord. This detachable as more clearlyshown in Figs; 4 and 5, comprises .a U-shaped body portion 32 receiving thestick 27 and attached thereto by means of pins 33 or'the like. Pivoted upon 7 this body Po tion 32 by means of pins 34, is a pair of jaws 39. The inner ends of these jaws are pivotally connected by a link 40, whereby they move together. The cord 18 is adapted to pass between to. be engaged thereby. The jaws carry downwardly extending fingers 41 having shoulders 42. These shoulders are engaged by a curved leaf spring 43, tending to the jaws inwardly toward each other. The leaf spring 43 is held against lateral movement by a plate 44, rigidly attached to the lppdy portion 32by means of pins 45 or the It is-obvious that by'moving the fingers 41 toward each other, the jaws 39 will'move designated as a whole move provided at its endsv with pins 29, ro-

these jaws and i apart, and release the c0rd'18,"thus perv same comprising jaws 46, pivoted to the body portion 32, as shown at 47. These aws have grooves 48 to receive the cord 18 and have interfitting extensions 49, pivotally connected by means of a pin 50. 'The jaws 4C6 carry outwardly extending fingers 51, connected by cords of flexible elements 52, as shown. A spring 53 engages shoulders 54 upon the jaws 4-6, and tends to swing them inwardly. A plate 55 is attachedto the body portion 32 and prevents lateral movement of the spring.

In operation, it is obvious that, when the lower sash frame 12 is raised and lowered, the cord 18 will move with it, the weight 20 and associated elements retaining it taut. This movement of the cord will of course move the shade 26 but the same may be again conveniently adjusted by manipulation of the clamp 31. When the upper sash frame 11 is moved upwardly, the curtain will unwind and when it is moved downwardly the curtain will wind upon the cylinder 28. The curtain may be moved up and down independently of the sash frame or frames.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred ex-- ample of the same,and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described the invention, I elaim:- 1. The combination with a window frame and a vertically movable sash frame arranged therein, of a flexible element connected with the vertically movable sash frame for movement therewith, automatic means to take up the slack in the flexible Games of this pater/s may be obtained for five cents each, by addressing the Washington, D. 0.

thereof and connected with the lower portion of the sash frame to be moved thereby,

automatic means to take up the slack in the flexible element upon the upward movement of the sash frame whereby the flexible element is retained taut, a self-winding shade arranged near the upper portion of the window frame, and adevice secured to the shade and adapted to have detachable clamping action with the flexible element whereby the shade may be held against movement with relation to the flexible element.

3. The combination with a window frame and a vertically movable sash frame arranged therein, of a pulley connected with the upper portion of the window frame, a flexible element passed about the pulley, a weight connected with one end of the flexible element, a lift element secured to the lower end of the sash frame and having a slot to receive the lower end of .the flexible element, a self-winding shade arranged near the window frame, and a clamping device carried by the shade and embodying a pair of oppositely arranged jaws to receive the flexible element therebetween.

In testimony whereof I afiix my signature in presence of two witnesses.
